Have the makings for a four element trapless Yagi that I need help to identify. My guess is that it is a Hy-Gain and probably at least 10 years old. The longest element side measures about 14 feet, give or take, and the boom is either 10 feet or I am missing a section. Four trapless elements. Odd thing is that they connect together with two machine screws through one side of the element as they nest together. No radiator hose clamps. Also in the box are four plastic clam shell type connectors that you lay the ends of the element into and bolt together with six nuts and bolts. The option looks like to provide some kind of seperation between the element pieces.Any help would be appreciated.Steve Harmon, N9HGFn9hgf@earthlink.net

Total estimated element length is about 14 foot for each side of the boom. That seems to be the longest element. I may be missing a boom section but it is typical 3" aluminum. One of the pieces has the Hy-Gain looking end cap as well. The element attachment pieces (where they attach to the boom) look exactly like Hy-Gain and there are those little plastic sleeves that fit over the ends of the elements and fit into the boom attachment pieces. You may be correct in that it is some kind of home brew affair, but made with Hy-Gain hardware. But most beams that I've had in the past had pass through hardware to attach the element components or use hose clamps. This provides two screw holes in each element section and uses sheet metal screws...Thanks for the commentsSteve, N9HGFn9hgf@earthlink.net

Can find no identification of any sort. It may just be a compilation of parts that fools you into thinking it's a complete antenna.

The odd things are that the elements are pieced together with two machine screws on one side only rather than pan head screws that go all the way through with a nut on the other side, or the typical radiator hose clamp arrangement...and there are four plastic clam shell sleeves that you can join two pieces of aluminum together with.

Well, by accident while looking for information on my Hy-gain Roto-Brake project, I chanced upon a drawing of a Hy-gain Big Gun quad. It looks like I'm on the right track but need to find a good readable manual.SteveN9HGF@earthlink.net
